Co-exposure of microplastics and heavy metals in the marine environment and remediation techniques: a comprehensive review.

Microplastics (MPs) and heavy metals are significant pollutants in the marine environment, necessitating effective remediation strategies to prevent their release into the sea through sewage and industrial effluent. This comprehensive review explores the current understanding of the co-exposure of MPs and heavy metal-enriched MPs, highlighting the need for effective remediation methods. Various mechanisms, including surface ion complexation, hydrogen bonding, and electrostatic forces, contribute to the adsorption of heavy metals onto MPs, with factors like surface area and environmental exposure duration playing crucial roles.

DESIGN OF IMMUNORADIOMETRIC ASSAY FOR GONADOTROPINS USING A COMMON DETECTION ANTIBODY: AN EXPERIENCE.

We share our experience in the development of immunoradiometric assay (IRMA) for gonadotropins, FSH and LH using common tracer concept. Commercially procured, monoclonal antibody against 'common epitope' of FSH and LH was radiolabeled and epitope specific monoclonal antibody against β-subunit of FSH and LH was chemically immobilized and used as a capture system. In an inclusive assay procedure developed, 100 µl of respective standard and specific capture antibody was incubated with 100 µl common tracer, for 3 h at RT with shaking.
