The Role of Microalgae in the Biogeochemical Cycling of Methylmercury (MeHg) in Aquatic Environments
Methylmercury (MeHg) is the most important and abundant organic Hg pollutant in aquatic ecosystem that can affect human health through biomagnification. It toxic form, which occurs naturally by human-induced contamination water further biomagnified food web. MeHg only form accumulates living organisms able to cross blood–brain barrier, presenting an enormous risk. Anthropogenic activity increas...
Microplastics (MPs) have been recognized as an environmental threat due to their persistence, ubiquity, and toxicity potential. Due small size, MPs are endowed with a large specific surface area, having the ability sorb accumulate other contaminants that co-exist them in aquatic environment it is case of pharmaceuticals. In this way, can act vectors, facilitating contact pharmaceuticals organis...
Mercury is one of the most dangerous toxicants for all living organisms, having a high degree biomagnification. The determination mercury concentration in different species fish important evaluation state aquatic ecosystems. aim research study peculiarities content Sheksna Reservoir, Sukhona River, Kubenskoye, Borovskoye and Svyatoye lakes. muscles Vologda Region varies from 0.0397 mg/kg to 1.1...
Environmental pollution caused by mercury has received increasing attention in recent years. Several studies have warned of the high rates biomagnification superior levels marine food networks affecting seabirds. Although seabird feathers are reported as bioindicators mercury, possibility using microbiota associated with them for bioremediation this metal not been considered. Despite potential ...
Abstract Plastics are widely used in daily lives but uncontrollably dumped into the ocean by humans. Plastic pollution is harmful to marine environment and organisms as it can break down microplastics (MPs) release chemicals water. Microplastics small, fragmented plastic pieces (< 5mm) that exist every part of ocean. MPs problematic because they hard recover be easily consumed organisms, res...
Lake Tanganyika is a globally important lake with high endemic biodiversity. Millions of people in the lake basin depend on several fish species for consumption. Due to the importance of fish consumption as an exposure route of mercury to humans, we sampled Lake Tanganyika in 2000 to assess total mercury concentrations and biomagnification of total mercury through the food web. Stable nitrogen ...
The thrust of this research study was to ascertain the physicochemical characteristic in settling particulate matter and sediments samples collected from wellington industrial estate flood plains; main objectives are as follows: determine hydrogen ion index (pH) area, electrical conductivity (EC) same location. Samples were six locations (at varying depths 0 - 5 cm 10 cm) sample area 1 (Welling...
Abstract Purpose of Review The concern mercury pollution and the impact that it poses on marine environment were studied heavily since case poison from Minamata bay in 1960s. present study provides an insight into cycle methylmercury bioindicators reflect exposure levels. paper also used driving forces, pressures, states, impacts, responses (DPSIR) analysis to evaluate global contamination prob...
