③ compared to the effective use of 100 mg·L-1 irrigation water containing Zn， the use of 20 mg·L-1 irrigation water containing Zn somewhat reduced the uptake and transportation of Cd in rice， together with translocation factor （TF） of Cd from rice roots to stems was also dramatically decreased by 12.5%-56.3%， utilizing the B1 and BF1 remedies achieving significant levels. These outcomes suggested that the use of irrigation water containing Zn could considerably decrease the uptake and accumulation of Cd in rice， together with application of 20 mg·L-1 irrigation water containing Zn prior to the booting and filling phase could effectively understand the safe creation of Cd-contaminated paddy fields.Novel Fe-Mn combined graphene oxide （GO-FM） product was created and tested for the efficacy in remediating farming soil co-contaminated by Cd so that as. In a 60-day earth incubation experiment， the remediation apparatus and immobilization effects of GO and GO-FM at various addition ratios （0.1%， 0.2%， and 0.3%） were investigated in Shangyu and Foshan soils， which had varying physicochemical properties and contamination degrees. The powerful alterations in pH， DOC concentration， bioavailable Cd and also as content， and morphology of Cd so that as were investigated to look for the remediation effectiveness associated with the materials. The outcomes demonstrated that compared with that into the empty control， GO-FM increased the pH in Shangyu soil but reduced the pH in Foshan earth. After tradition， both GO and GO-FM increased the soil DOC material. GO-FM decreased the dissolvable Cd concentration by 5.08%-19.19% and also the bioavailability of Cd by 36.57%-42.8% in Foshan earth， plus the main immobilization method ended up being electrostatic adsorption， complexaCd so when co-contamination in numerous forms of soil.In purchase to study the safe usage of acid cadmium （Cd） contaminated soil， light and reasonable Cd-contaminated farmland in Shangluo， Shaanxi Province had been Minimal associated pathological lesions taken once the study object， and lime， biochar， and calcium magnesium phosphate fertilizer were used. Through the wheat-maize rotation test， the safe application selleck chemicals effectation of different levels of passivator on Cd-contaminated soil was investigated， and also the most useful ratio of passivator ended up being selected. The outcomes showed that： ① the earth quality might be enhanced to varying degrees by making use of the passivator. ② following the application of amendments， the grain yield of wheat and maize increased to different degrees. ③ The lime 2 340 kg·hm-2 （C3） treatment had the greatest effect， which enhanced the soil pH of wheat and corn by 1.453 and 1.717 units， respectively， and paid off the available Cd content by 34.38% and 30.20%， correspondingly. ④ The application of biochar 1 800 kg·hm-2 （B2） treatment had ideal influence on reducing the Cd contents in grain origins， straws， and grains， which were significantly paid down by 53.60%， 38.86%， and 52.96%， respectively， compared with this in CK. The Cd content in grain grains ended up being paid off to 0.09 mg·kg-1， that has been lower than the restriction value of wheat Cd （0.1 mg·kg-1） specified in the “National food protection standard food pollutant limit” （GB 2762-2017）. The use of the biochar 1 260 kg·hm-2 （B1） therapy had the best extensive influence on decreasing the Cd items of maize origins， straws， and grains， which had been significantly reduced by 43.74%， 53.20%， and 94.57%， respectively， compared with that in CK. The Cd content of maize grains ended up being decreased to 0.001 9 mg·kg-1， which ended up being less compared to the limitation value of maize Cd （0.1 mg·kg-1） specified into the “National food safety standard food pollutant limit” （GB 2762-2017）. Therefore， under the circumstances associated with the field experiment， thinking about the impact of various indexes， biochar had ideal effect on farmland soil into the wheat-maize rotation area with mild to moderate Cd pollution.A farmland area in Zhaotong City had been taken since the study object， plus the method of point-to-point collaborative sampling had been used to collect farmland soil and vegetables in Zhaotong and test the information of six heavy metals， particularly As， Pb， Cu， Zn， Cd， and Cr. The geo-accumulation list and possible environmental danger list were utilized to judge the heavy metal air pollution of soil. Medical risk design ended up being utilized to judge the risk to the human anatomy imposed by vegetables. The outcomes High Medication Regimen Complexity Index revealed that Cu， Zn， Pb， Cd， and Cr air pollution existed when you look at the research location. Compared with the risk testing worth of farmland， the over-standard rates were 34.35%， 6.87%， 2.29%， 80.15%， and 6.11%， respectively； Pb， Cd， and Cr were present in vegetables. Weighed against the pollutant limitation in meals， the over-standard prices were 6.87%， 15.27%， and 36.64%， respectively. In line with the earth pollution evaluation， Cd within the earth showed a solid environmental risk， and other heavy metals into the soil showed a mild environmental danger. The peoples wellness risk analysis model revealed that both non-carcinogenic threat and carcinogenic risk had been out from the appropriate range along with a greater impact on young ones. Correlation analysis showed that as with the soil had an antagonistic influence on Cu and Zn absorption by vegetables， whereas Cr when you look at the soil could advertise Cu and Zn consumption by vegetables.Tetrachloroethylene （PCE） and trichloroethylene （TCE） tend to be typical volatile halogenated organic compounds in groundwater that pose serious threats to the environmental environment and human wellness.
