Multicolor fluorescence in situ hybridization (M-FISH) is a powerful cytogenetic technique that enables researchers to visualize and analyze multiple DNA sequences within a cell simultaneously. Combining the principles of traditional FISH with advanced fluorescence microscopy, M-FISH offers unparalleled insights into chromosomal structures, genetic variations, and the intricate architecture of ...
Estuarine eutrophication as a result of agricultural land use including the use of chemical fertilizers is increasing worldwide. Prince Edward Island, Canada has very high agricultural intensity by international standards with approximately 44% of the land area under production, and some watersheds in excess of 75% agricultural land‐use. The type of agriculture is also intensive with primarily ...
Consumption of fish and aquatic products is considered to be the main pathway of human exposure to methylmercury (MeHg). To assess human health risk through seafood consumption in a coastal area of Guangdong Province, South China, a total of 518 seafood samples (including fish, shrimp, crabs, and mollusks) were collected from 11 coastal cities for total mercury (THg) analysis. The THg ...
Portions of the Santa Maria River and Oso Flaco Creek watersheds in central California, USA, are listed as impaired, under section 303(d) of the Clean Water Act, and require development of total maximum daily load (TMDL) allocations. These listings are for general pesticide contamination, but are largely based on historic monitoring of sediment and fish tissue samples that showed contamination by ...
The annual cultivation pattern in the Uma‐oya catchment in Sri Lanka is characterized by Yala and Maha rainfall periods and associated cropping. Two cultivation seasons were compared for pesticide residues: base flow, field drainage, and the runoff and supplementary sediment data for three sites in the catchment. Organophosphate and N‐methyl carbamate pesticide analysis confirmed a higher ...
Abstract In a long-term program polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) as well as dioxin-like polychlorinated biphenyls (DL-PCBs) were analyzed in the muscle tissue of eels (Anguilla anguilla), bream (Abramis brama), European chub (Leuciscus cephalus) and ide (Leuciscus idus) from the river Elbe and its tributaries Mulde and Saale. The variation of the ...
