An organism's fitness critically relies on its immune system to provide protection against parasites and pathogens. The has reached highest complexity in vertebrates, combining the highly specific adaptive with non-specific innate immunity. In a complex of steroid hormones regulates major physiological functions comprising energy metabolism, growth, reproduction performance. This allows organism allocate available according life-history traits environmental conditions, thus maintaining homeostasis survival individual population. Immune activation must take into account developmental stage nutritional state organism. It should respond adequately different pathogens, but not overperform or consume all resources for other functions. important trade-off between immunity is balanced by oestrogen. Many thousands chemicals released humans environment, so-called xenobiotics, have ability disrupt normal endocrine function. Such endocrine-disrupting been demonstrated impair reproductive be responsible numerous diseases wild life. Given that oestrogens are established modulators cell populations, exogenous oestrogen mimics can modulate aquatic animals, such as fish, potentially affecting wildlife aquaculture. review highlights interaction xenoestrogens fish particularly focusses thymus, primary organ, European seabass, Dicentrarchus labrax an species, both fisheries

The pervasiveness of microplastics (MPs) in terrestrial and aquatic ecosystems has become a significant environmental concern recent years. Because their slow rate disposal, MPs are ubiquitous the environment. As consequence indiscriminate use, landfill deposits, inadequate recycling methods, MP production accumulation expanding at an alarming rate, resulting range economic, social, repercussions. Aquatic organisms, including fish various crustaceans, consume MPs, which ultimately consumed by humans tertiary level food chain. Blocking digestive tracts, disrupting behavior, reducing reproductive growth entire living organisms all consequences this phenomenon. In order to assess potential impacts resources required for life plastic product, importance cycle assessment (LCA) circularity is underscored. MPs-related ecosystem degradation not yet been adequately incorporated into LCA, tool evaluating performance product technology cycles. It technique that designed quantify effects from its inception demise, it frequently employed context plastics. control necessary due growing pose as newly emergent threat. This use. paper provides critical analysis formation, distribution, methods used detecting MPs. on human health also discussed, posed great challenge conduct LCA related socio-economic management discussed. paves way understanding ecotoxicological emerging threat associated issues limits impact plastic.
