Owing to various industrial applications of mercury (Hg), its release into the environment at high concentration is becoming a great threat living organisms on global scale. Human exposure Hg greatly correlated with contamination in food chain through cereal crops and sea foods. Since non-essential component does not possess biological role exhibits carcinogenic genotoxic behaviour, biomonitoring focus biomagnification higher animals plants need hour. This review traces plausible relationship between concentration, chemical form, exposure, bioavailability, bioaccumulation, distribution, ecotoxicology. The toxicity molecular mechanisms, oxidative stress (OS), protein alteration, genomic change, enzymatic disruptions are discussed. In addition, this also elaborates advanced strategies for reducing such as algal phytoremediation, biochar application, catalytical oxidation, immobilization. Furthermore, there challenges overcome future perspectives considering concentrations, biomarkers, identification nature exposures recommended.

Considerable amounts of polyethylene terephthalate (PET) microplastic fibers are released into the environment by laundering polyester clothing. Microplastic can be ingested organisms in environment. Therefore, it has been suggested that act as vectors for adsorbed contaminants, which subsequently desorbed gut organism. We undertook sorption isotherm experiments at pH 6, 7, and 8 to quantify methylmercury (MeHg) PET fibers. Sorption isotherms were fit Langmuir, Freundlich, Brunauer-Emmett-Teller models. decreased with increasing pH, explained physisorption on negatively charged surfaces greater presence neutral or MeHg species higher pH. used parameters obtained model fits predict likely concentration aquatic ecosystems environmentally realistic concentrations. calculated concentrations four orders magnitude lower than previously observed seston (suspended particles comprising algae bacteria) base food web.

Mercury (Hg) poses significant risks to human health, the environment, and plant physiology, with its effects influenced by chemical form, concentration, exposure route, organism vulnerability. This study evaluates physiological impacts of Hg on Handroanthus impetiginosus (Ipê Roxo) seedlings through SPAD index measurements, chlorophyll fluorescence analysis, quantification in tissues. Four-month-old were exposed for eight days distilled water containing at 0, 1, 3, 5, 7 mg L−1. The decreased 28.17% L−1, indicating reduced photosynthetic capacity. Chlorophyll a analysis revealed 50.58% decline maximum efficiency (Fv/Fm) 58.33% reduction quantum yield (ΦPSII) along an 83.04% increase non-photochemical quenching (qn), suggesting oxidative stress PSII damage.

Amid the growing concerns about air toxics from pollution sources, much emphasis has been placed on their impacts human health. However, there limited research conducted to assess cumulative country-wide impact of both terrestrial and aquatic ecosystems, as well complex interactions within food webs. Traditional approaches, including those United States Environmental Protection Agency (US EPA), lack versatility in addressing diverse emission sources distinct ecological repercussions. This study addresses these gaps by introducing Ecological Health Assessment Methodology (EHAM), a novel approach that transcends traditional methods enabling comprehensive detailed regional risk assessments across ecosystems. EHAM also advances field developing new food-chain multipliers (magnification factors) for localized ecosystem web models. Employing multimedia assessment toxics’ fate transport techniques its foundation, this extends US EPA methodologies broader range sources. The quantification estimation employs quotient method, which yields an screening (ESQ). Utilizing Kuwait case application methodology, study’s findings data 2017 indicate substantial Kuwait’s coastal zone, with ESQ values reaching high 3.12 × 103 carnivorous shorebirds, contrasted negligible risks inland production zones, where all groups are consistently below 1.0. By analyzing toxicity reference value (TRV) against expected daily exposure receptors toxics, proposed methodology provides valuable insights into potential subsequent populations. present contribution aims deepen understanding health implications lay foundation informed, ecology-driven policymaking, underscoring need measures mitigate impacts.
