Tangshan is known as a typical heavy industrial city with serious atmospheric pollution.It suffers the most pollution during winter heating period.This study aims to explore level and spatial distribution of element deposition in area validate suitability Ramalina sinensis (RSI) an active biomonitor North China cities. RSI was transplanted (Dec.2016-Mar.2017) exposed for 17 weeks.The concentration 51 elements tested using ICP-MS (inductively coupled plasma mass spectrometer).The results showed that exposure all but Ag significantly higher than background value.Principal component analysis (PCA) K, P, Rb were separated into group G5, these nutrients have lower bioaccumulation other groups.The remaining 47 classified groups G1 (Al, Be, Co, Cr, Cs, Ge, Li, Nb, Ni, Si, Th, Ti, U, V, 16 rare earth La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Y, Sc) crustal origin, G2 (Ca, Cd, Cu, Mg, Mn, Mo, S, Sb, Sr, Zn) G3 (Bi, Pb, Sn) G4 (As, Fe, Se, Tl) crustal-atmospheric origin.The overall moderate (PLI zone = 2.010 combined G1-4), highest (high severe) G2.The concerned are Ca which high at regional scale.All show similar pattern characterized by decreasing from east west rural urban areas.These indicate good elements, barring some nutrients.The importance should be emphasized indicator anthropogenic emissions lichen-active biomonitoring techniques cities.The experienced certain degree pollution, contributed mainly frequent agricultural activities coal combustion areas around.This first monitor cities lichen method.

Introduction In recent years, cadmium pollution has increasingly serious impacts on aquatic environments, directly threatening the health and growth of freshwater fish causing significant economic losses to aquaculture industry. However, there is limited research effects gut-liver axis hepatotoxicity in fish. Therefore, this study investigated potential toxic induction through largemouth bass. Methods This experiment was divided into four groups, each with different concentrations solution added water (0.00 mg/L, 1.024 1.537 2.306 mg/L), three replicates per group, a feeding period 42 days. Results discussion The findings indicate decline performance bass under stress (P<0.05). Cadmium-induced oxidative inhibited activity antioxidant enzymes, activated Nrf2-Keap1 pathway, resulting increased levels MDA ROS, decreased activities CAT, GSH-PX, SOD as well related gene expressions Additionally, down-regulated expression IL-10 up-regulated IL-15, IL-8, IL-1β, TNF-α, MT, indicating an inflammatory response liver Tissue section observations after revealed hepatocyte nuclear condensation, cell degeneration, necrosis, vacuolization, shortened intestinal villi epithelial metaplasia. Furthermore, barrier-related proteins ZO-1 Occludin (P<0.05), reducing microbial diversity. Correlation analysis close relationship between microbiota hepatic immune factors. summary, can disrupt barrier, alter structure microbiota, may potentially play role toxicity liver.
