Human Health Risk Assessment of Chlorinated Hydrocarbons in Groundwater Based on Multi-Pathway Analysis

Toxics, Год журнала: 2024, Номер 12(12), С. 894 - 894

Опубликована: Дек. 9, 2024

The rapid development of the global chemical industry has led to widespread groundwater contamination, with frequent pollution incidents posing severe threats water safety. However, there been insufficient assessment health risks posed by chlorinated hydrocarbon contamination in around industrial parks. This study evaluates at a park and conducts multi-pathway risk assessment, identifying key pollutants. In addition, sensitivity analysis primary exposure pathways was performed using Monte Carlo method. results indicate exceedance pollutant concentrations diffusion. Carcinogenic were mainly driven vinyl chloride, whose oral cancer slope factor significantly higher than that other substances, while non-carcinogenic dominated trichloro-ethylene, which had lowest reference dose. Both carcinogenic through drinking pathway accounted for approximately 90% total risk, whereas contribution from dermal contact negligible. Although boiling can partially reduce risks, its effect on high-concentration pollutants is limited. Additionally, showed concentration influencing values, followed duration. findings this provide scientific basis effectively formulating control measures ensuring safety nearby residents.

Exploring the Possibilities of Using Recovered Collagen for Contaminants Removal—A Sustainable Approach for Wastewater Treatment

Polymers, Год журнала: 2024, Номер 16(20), С. 2923 - 2923

Опубликована: Окт. 18, 2024

Collagen is a non-toxic polymer that generated as residual product by several industries (e.g., leather manufacturing, meat and fish processing). It has been reported to be resistant bacteria have excellent retention capacity. However, the recovered collagen does not meet requirements used for pharmaceutical medical purposes. Due scarcity of water resources now affecting all continents, pollution major concern. Another field could integrate by-product wastewater treatment. Applications collagen-based materials in treatment discussed detail, comparisons with already frequently made. Over last years, tested removal both organic substances, dyes) inorganic compounds heavy metals, noble uranium). They also manufacture oil-water separation materials; therefore, they emulsified oily wastewater. Because analysed wide range good candidates removing contaminants from streams seasonal variations composition concentration. The use makes method eco-friendly cost efficient. This paper discusses some challenges related treatment: material stability, reuse disposal. results showed are renewable reusable without significant loss initial properties. In sorption processes, incorporation experiments real demonstrated there competition among substances present sample.

Evaluation of Heavy Metal Contamination in Black Soil at Sanjiang Plain: From Source Analysis to Health Risk Assessment

Processes, Год журнала: 2024, Номер 12(12), С. 2829 - 2829

Опубликована: Дек. 10, 2024

Heavy metals were discharged into the agricultural soil through coal mining, transportation, etc., posing a threat to human health food chain. In order investigate sources of heavy and potential risk population, we collected 298 surface samples in black area Sanjiang Plain Heilongjiang province tested concentrations seven metals. Toxic element contamination was evaluated by combining ecological index environmental capacity, pollution are identified positive matrix factorization. The results indicate that Cd As exceed background values 1.74 1.51 times, respectively, is significantly higher than those other toxic elements. comprehensive level moderate at 78.5% low 21.5%. metal elements include pesticide spraying (36.5%), input fertilizer transport activities (20.5%), mining metallurgy-related (43.1%). When linking PMF Human Health Risk Assessment model, it found about 56% pose carcinogenic children. Knowledge can certainly help understand risks people provide scientific basis for prevention pollution.

Physiological parameters and metal-accumulating capacity of the biofuel plant Miscanthus × giganteus cultivated on oil-contaminated podzol soil treated with humic preparations

Studia Biologica, Год журнала: 2024, Номер 18(4), С. 139 - 156

Опубликована: Дек. 1, 2024

Background. Physiological characteristics of the biofuel plant Miscanthus × giganteus J. M. Greef, Deuter ex Hodk. & Renvoize are currently attracting much attention due to its phytoremediation potential. The aim this work was study content photosynthetic pigments in leaves giganteus, accumulation metals rhizosphere and aboveground organs, as well morphological parameters plants cultivated on oil-contaminated soil exposed treatment with humic preparations. Materials Methods. During field experiments, five experimental plots (PC P1–P4) an area 1 m2 were laid out podzol territory adjacent Starosambirske oil field. PC plot not subjected any treatment. P1 planted rhizomes; soils P2–P4 contaminated 10 L/m2 crude then rhizomes. Before planting rhizomes P3 P4, these soaked solutions Fulvital® Plus Liquid Humifield® Forte, respectively. growth period, sprayed twice Shoot height leaf width, a- b-type chlorophyll (Chla Chlb, respectively), total (Chla+b) carotenoid concentrations measured using standard methods. (Ca, Cr, Cu, Fe, K, Mg, Mn, Ni, Pb, Zn) samples assessed by X-ray fluorescence analysis Elvax Light SDD Analyzer. Results. cultivation did affect shoot or width plants, but it reduced Chla, Chla+b carote­noids leaves. Treatment preparations led increase pigment at different periods. Oil-contaminated showed elevated levels Cr Ni. treated resulted increased Ca, Mn Ni contents plot. Growing significant decreases Zn stems. mentioned stems concentration Mg from compared those untreated plants. According bioaccumulation factor (BF) values, have a high potential for Ca (BF>1), medium K (BF 0.1 0.32) low Fe (BF<0.1). BF values decreased when grown soil. Conclusions. Humic preparation has positive effect physiological ability extract may mediate plant’s In regard, combination will be promising lands petroleum products.
