Based on the characteristics and effective components of steel slag desulfurization gypsum, a new type permeable reactive material was prepared by combining simulation experiment arsenic- antimony-contaminated groundwater remediation carried out. A combination X-ray fluorescent, BGRIMM Process Mineralogy Analyzing System (BPMA), ICP-MS, SEM-EDS detection analysis methods used to investigate effects particle size, gypsum ratio, slag-desulfurization mixed test block size performance wall remove arsenic antimony. The results show that composed (−4.75 + 1.18 mm) (−13.2 9.5 in 4:1 ratio achieved removal rates 91.85% for As 90.58% Sb, reducing their concentrations below drinking water standard. purpose using intercept heavy metals toxic ions surface runoff achieved. Arsenic adsorbed, physically encapsulated, lattice solidified C-S-H gel. This research provides cost-effective environmentally friendly solution storage while addressing metal pollution groundwater.

As a crucial organ of the female reproductive system, ovary has both and endocrine functions. Oxidative stress refers to an increase in intracellular reactive oxygen species (ROS), which play role normal physiological activity ovary. However, excessive ROS can cause damage With advancement human industrial activities, heavy metal pollution become increasingly severe. Heavy metals oxidative through direct indirect mechanisms, leading changes signal transduction pathways that ovaries. This review aims outline adverse effects on ovaries triggered by such as copper, arsenic, cadmium, mercury, lead. The detrimental include follicular atresia decreased estrogen production experimental animals, they also premature ovarian insufficiency women. Additionally, this discusses antioxidants, provides some treatment methods, summarizes limitations current research, offers perspectives for future research directions.
