个人简介:My special research interest lies in the development of trace analytical methods for the detection and identification of emerging contaminants in natural waters. Environmental analysis demands sensitive and robust methods to enable a successful research on the occurrence and fate of contaminants in the water cycle. Environmental analytics is not only the door-opener for many research questions but above all it is also my personal passion. My research covers the following topics in analytical and environmental chemistry, including target, suspect and non-target screening of organic contaminants in natural waters by liquid chromatography coupled to high resolution mass spectrometry; Development of software workflows for the mining of high resolution mass spectrometry data; Hyphenation of gas and liquid chromatography with mass spectrometry (Orbitrap, ToF, TripleQuad instruments) and/or ion mobility spectrometry (IMS) using available atmospheric pressure interfaces (ESI, APCI, APPI, APGC); Advancement of existing active and passive sampling techniques for surface waters; Online coupling of sample preparation with LCMS detection for high-throughput measurements of field study samples; Localization of sources and input pathways of chemicals discharged into surface water by households, agriculture and industry; Determination of the occurrence, fate and behavior of emerging contaminants in natural water systems.

内容简介:The ubiquitous presence of micropollutants in environmental water samples and their potential (eco-)toxicological risk to humans and aquatic organisms even at the ng per Liter level have caused extensive research activities in this field over the last decades. The major challenge for the analysis of organic micropollutants and their transformation products in water bodies is the sensitive detection of the large number of chemical structures with diverse physico-chemical properties. To tackle this challenge, liquid chromatography coupled to high resolution mass spectrometry (LC-HRMS) is nowadays the method of choice due to its capability to screen simultaneously for target, suspect and non-target compounds. Sample enrichment is often required and a key factor for a sensitive detection. The use of powerful liquid chromatographic separation techniques, like reversed phase chromatography, is advantageous for matrix-rich water samples. Modern high-resolution mass spectrometers like Time-of-Flight (ToF) or Orbitrap instruments enable the sensitive acquisition of full scan spectra (MS and MS/MS) with high resolving power (>40’000) and high mass accuracy (<1ppm). Adequate data processing workflows comprises data pre-processing steps (i.e. peak detection, blank subtraction, isotope and adduct grouping) and prioritization of the pre-processed data (i.e. by mass defect, time or spatial trends) as well as identification of prioritized components (i.e. by library searches, in-silico predictions, meta information). Appropriate method applications involve many different steps from sample preparation to quantification of target compounds up to identification of unknown substances. Whereas such complex workflows can be reasonable well managed for limited sample sets of controlled lab studies, monitoring applications of such complex analytical methods within field study campaigns with a large number of matrix-rich samples becomes challenging. To illustrate the capabilities of LC-HRMS for such ‘real-world applications’, suitable workflows as well as selected projects dealing with target, suspect and non-target screening approaches in waste water, surface water and ground water will be presented.

Büsgen-Institute

Agricultural Soil Science

Georg August University of Göttingen, Germany

个人简介:Prof. Yakov Kuzyakov worked in various Soil and Environmental Science departments of universities and research institutes worldwide: Germany, USA, UK, Russia and China. Yakov’s expertise covers soil ecology, biogeochemistry, rhizosphere processes, C and N cycling, soil degradation, land use and agroecology. Yakov led research projects in many countries such as Germany, China, Korea, Tanzania, Indonesia, Russia and Chile.

Together with his group, Yakov focuses on soil biogeochemistry with long-term and deep expertise for processes of C and N cycles, priming effects and nutrient mobilization. His special interests are in soil – plant – microbial interactions in soil hotspots – locations with very high activity and abundance of microorganisms like rhizosphere, detritusphere, biopores. Yakov groundbreaking works are in the fields of rhizodeposition, fate of low molecular weight organic substances in soil, priming effects, visualization of enzyme activities, localization of root exudation. These processes are studied depending on land use and soil degradation, as well as such global change components as temperature, drought, elevated CO2 in the atmosphere. Yakov group made many innovative studies to pedogenic carbonates, biochar stability, competition of roots and microorganisms for nutrients, microbial metabolism in soil, effects of plant photosynthesis on CO2 efflux from soil. The applied studies are focused on C sequestration, soil fertility improvements, and reforestation effects.

To investigate these processes and understand mechanisms, Yakov group use a broad range of stable (13C, 15N) and radioactive (14C, 33P, 137Cs) isotopes applications including pioneering position specific labeling and combine these approaches with biomarkers (PLFA, amino sugars, neutral sugars) as well as microbial activity parameters (enzyme and respiratory activities, microbial growth rates).

Yakov has been and is an active member of several editorial boards, for top-ranked journals including Land Degradation and Development, Soil Biology and Biochemistry, European Journal of Soil Biology, Biogeosciences, Rhizosphere, Scientific Reports etc. He was awarded in 2015 the John Waid Award for Best Review Paper in Soil Biology & Biochemistry, 2016 the European Geosciences Union Outstanding Editor Award etc. He has/had more than 25 Highly Cited and 5 Hot Papers. Yakov is Visiting Professors and has very close and intensive collaboration with various top universities and research institutes in China.

内容简介:Biochar stability and decomposition of are fundamental to understand its persistence in soil, its contribution to carbon (C) sequestration, and thus its role in the global C cycle. Our current knowledge about the degradability of biochar, however, is limited. Using 128 observations of biochar-derived CO2 from 24 studies with stable (13C) and radioactive (14C) carbon isotopes, we meta-analyzed the biochar decomposition in soil and estimated its mean residence time (MRT). The decomposed amount of biochar increased logarithmically with experimental duration, and the decomposition rate decreased with time. The biochar decomposition rate varied significantly with experimental duration, feedstock, pyrolysis temperature, and soil clay content. The MRTs of labile and recalcitrant biochar C pools were estimated to be about 108 days and 556 years with pool sizes of 3% and 97%, respectively. These results show that only a small part of biochar is bioavailable and that the remaining 97% contribute directly to long-term C sequestration in soil. The second database (116 observations from 21 studies) was used to evaluate the priming effects after biochar addition. Biochar slightly retarded the mineralization of soil organic matter (SOM; overall mean: -3.8%, 95% CI = -8.1…-0.8%) compared to the soil without biochar addition. Significant negative priming was common for studies with a duration shorter than half a year (-8.6%), crop-derived biochar (-20.3%), fast pyrolysis (-18.9%), the lowest pyrolysis temperature (-18.5%), and small application amounts (-11.9%). In contrast, biochar addition to sandy soils strongly stimulated SOM mineralization by 20.8%. This indicates that biochar stimulates microbial activities especially in soils with low fertility. Furthermore, abiotic and biotic processes, as well as the characteristics of biochar and soils, affecting biochar decomposition are discussed. We conclude that biochar can persist in soils on a centennial scale and that it has a positive effect on SOM dynamics and thus on C sequestration.

Community Health Risk Assessment of Toxic Air Contaminants in California

地点:

第二主教学楼B102

时间:

17:10-18:00

报告人:

许凡博士

单位:

Department of Chemistry and Biochemistry, Old Dominion University

个人简介:Dr. Fan Xu has extensive experience in air quality and exposure assessment. Projects include health risk assessments for various manufacturing facilities and transportation projects, CEQA (California Environmental Quality Act) air quality analyses for developmental projects, ambient and indoor air quality investigation for schools, commercial buildings, and residential houses, workers’ chemical exposure evaluation, etc. She is specialized in health risk analysis, air dispersion modeling, emission estimation for mobile and stationary sources, and air monitoring. Dr. Xu previously worked at Ramboll USA Corporation and recently joined an air quality management agency. She has a bachelor’s degree in Environmental Planning and Management and a master’s degree in Environmental Engineering from Nankai University and a PhD degree in Health Sciences from Purdue University. She is a Certified Industrial Hygienist.

内容简介:Air toxics tend to pose greater risks in urban areas because these areas have a higher concentration of emission sources and a large number of people are exposed. Health risks are a measure of the chance that people will experience health problems. Exposure to toxic air contaminants (TACs) can increase risks of cancer and noncancer effects. A Health Risk Assessment (HRA) is the process that is used to evaluate how toxic emissions are released from a facility, how they disperse throughout the community, and the potential for those toxic pollutants to impact human health. In California, HRAs must be prepared for facilities in the priority list, which is based on the toxicity and quantity of released TACs and the proximity of the facility to potential receptors under the Air Toxics “Hot Spots” Information and Assessment Act (also known as AB2588). An AB2588 HRA conducted for a lead-acid battery recycling facility located near downtown Los Angeles will be discussed. In California, HRAs are also performed for developmental projects as part of the Environmental Impact Reports (EIRs) under the California Environmental Quality Act (CEQA), when deemed necessary. In most cases, such projects involve mobile sources. A freeway expansion project will be discussed to demonstrate the HRA methodologies in evaluating the mobile source emissions. The two case projects demonstrate the procedures laid out in the guideline that the Office of Environmental Health Hazard Assessment (OEHHA) of California Environmental Protection Agency developed, including hazard identification, exposure scenario and pathway consideration, receptor inclusion, dose-response, and risk calculation algorithms. The applicability in China of OEHHA’s HRA methodology will also be discussed.
