Decadal variations in natural and anthropogenic aerosol optical depth over the Bay of Bengal: the influence of pollutants from Indo-GangeticPlain.

Environ Sci Pollut Res Int 2021 Jun 15. Epub 2021 Jun 15.

CSIR-National Institute of Oceanography, 176 Lawsons Bay Colony, Visakhapatnam, 530017, India.

Perennial increase in atmospheric pollution over the Bay of Bengal (BoB) and South China Sea is reported due to increase in human population and industrial activity in South and Southeast Asia. Based on total aerosol optical depth (AOD) derived from MODIS (moderate resolution imaging resolution imaging spectroradiometer), natural and anthropogenic fractions were derived. The seasonality and spatial variability in rate of increase in total, natural, and anthropogenic AOD fractions were examined over the BoB using data collected between 2001 and 2019. Read More

Bacterial contribution to 17β-estradiol mineralization in lake sediment as revealed by C-DNA stable isotope probing.

Environ Pollut 2021 Jun 2;286:117505. Epub 2021 Jun 2.

State Key Laboratory of Soil and Sustainable Agriculture, Institute of Soil Science, Chinese Academy of Sciences, Nanjing, 210008, PR China.

The accumulation of estrogens in aquatic environments has drawn increasing public concern due to their adverse effects on aquatic ecosystems and human health. Bacteria play important roles in eliminating estrogens from the environment, but knowledge of the identity and functions of the microorganisms involved in metabolizing these steroid hormones in the natural microbial communities is lacking. Here, we added C-17β-estradiol (C-E2) to sediments collected from Zhushan (ZS) Bay, Meiliang (ML) Bay, Gonghu (GH) Bay, and the central area (CA) of the Taihu Lake. Read More

Analysis of Polycyclic Aromatic Hydrocarbons and Phthalate Esters in Soil and Food Grains from the Balkan Peninsula: Implication on DNA Adduct Formation by Aristolochic Acid I and Balkan Endemic Nephropathy.

Environ Sci Technol 2021 Jun 14. Epub 2021 Jun 14.

Department of Chemistry and Division of Environment and Sustainability, The Hong Kong University of Science and Technology, Clear Water Bay, Kowloon 000000, Hong Kong.

Balkan endemic nephropathy (BEN) is a chronic tubulointerstitial nephropathy affecting residents of rural farming areas in many Balkan countries. Although it is generally believed that BEN is an environmental disease caused by multiple geochemical factors with much attention on aristolochic acids (AAs), its etiology remains controversial. In this study, we tested the hypothesis that environmental contamination and subsequent food contamination by polycyclic aromatic hydrocarbons (PAHs) and phthalate esters are AA toxicity factors and important to BEN development.

First dynamics of bacterial community during development of Acropora humilis larvae in aquaculture.

Sci Rep 2021 Jun 3;11(1):11762. Epub 2021 Jun 3.

Department of Microbiology, Faculty of Science, Chulalongkorn University, Phyathai Road, Pathumwan, Bangkok, 10330, Thailand.

A symbiosis of bacterial community (sometimes called microbiota) play essential roles in developmental life cycle and health of coral, starting since a larva. For examples, coral bacterial holobionts function nitrogen fixation, carbon supply, sulfur cycling and antibiotic production. Yet, a study of the dynamic of bacteria associated coral larvae development is complicated owning to a vast diversity and culturable difficulty of bacteria; hence this type of study remains unexplored for Acropora humilis larvae in Thai sea.

Environ Sci Pollut Res Int 2021 May 25. Epub 2021 May 25.

Faculty of Technology and Metallurgy, University of Belgrade, Karnegijeva 4, Belgrade, 11120, Serbia.

Surface sediments collected from twelve stations in the Boka Kotorska Bay were analyzed for the level and distribution of twenty-six elements and ten oxides, grain sizes, organic matter, and carbonate content. Potentially toxic elements (Al, Fe, Mn, Cr, Zn, Ni, Cu, Pb, As, Co, U) were determined to assess the contamination status and potential environmental risk according to the single-element indices (enrichment factor (EF), geoaccumulation index (Igeo), contamination factor (CF)), and combined index (pollution load index (PLI)). The single-element indices EF and CF revealed that the surface marine sediment was moderately polluted with Pb, Cu, and Cr, while Igeo indicated moderate pollution with Ni > Cr > Zn > Cu > As and moderate to heavy pollution with Pb, as a result of the anthropogenic factors.
