Pollution of residual plastic film in arable lands is a severe problem China. In this study, the status and influential factors were investigated using methods farm survey combination with questionnaires quadrat sampling at large number field sites Xinjiang Uygur Autonomous Region, The results showed that amount utilization increased largely reached to 1.8×105 t 2013. Similarly, mulching area also substantially recent decades, 2.7×105 ha same year. According current survey, 60.7% presented...
Water quality is a big concern for the humankind as it most important natural resource. polluted by increasing activities of population and necessity to provide them with goods services that use water vital In this study, surface samples were collected in summer winter season from Rupsa river, Bangladesh, pH, electrical conductivity (EC), Cr, Ni, Cu, As, Cd Pb concentrations analyzed assess metal toxicity, identify possible sources determine health risk metals water. During season, mean Pb,...
Abstract Poyang and Dongting Lakes are two important river-connecting lakes with a complicated water system pattern in the middle reaches of Yangtze River, China. Recently, extreme drought events occurred frequently lakes. This study analyzed characteristics differences hydrological droughts during period 1964–2016 explored correlation between large-scale climate indices. The results showed that became increasingly serious. Especially after 2003, both entered dry season earlier intensity was...
Urban forest soil infiltration, affected by various factors, is closely related with surface runoff. This paper studied the effect of urban types, vegetation configuration and properties on infiltration. In our study, 191 typical plots were sampled in Changchun City, China to investigate infiltration characteristics its influencing factors. Our results showed that steady rates highly variable. High variations final observed for different patterns compaction degrees. Trees shrubs grasses had...
Plant nitrogen (N) and phosphorus (P) resorption is an important strategy to conserve N P in the face of nutrient limitation. However, little known about variation efficiency (NRE PRE) their correlation with leaves soil C:N:P stoichiometry black locust forests (Robinia pseudoacacia L.) different ages. In this study, we measured C, N, concentrations soil, green leaves, senesced from ages (i.e, 10-, 20-, 30-, 36-, 45-year-old), calculated NRE, PRE, ratios. The NRE PRE tended increase then...
Drought–flood abrupt alternation (DFAA) is one of the remarkable manifestations summer monsoon anomaly at subseasonal scale and can result in severe damage. This study identified analyzed DFAA terms streamflow Poyang Lake catchment over last 50 years based on a index (DFAAI). The also investigated intra-annual distribution characteristics long-term tendencies associated with DFAA, as well relationship precipitation patterns. A statistical analysis showed that drought-to-flood events...
Abstract Vegetable gardens are increasingly common in urban areas and can provide numerous societal benefits; however, contamination with potential toxic elements (PTEs) due to urbanization industrialization is cause for concern. The present study aimed assess the source of pollution levels garden soils, as well health risks adults children consuming vegetables grown such environments. Various types vegetable samples their corresponding soils from 26 community were collected throughout...
This study aimed to investigate and discuss the occurrence accumulation of mercury in fruiting bodies wild-growing fungi (Macromycetes) collected from montane forests two regions southwestern China with differences soil geochemistry, climate geographical conditions. Fungal mycelia soils subalpine region Minya Konka (Gongga Mountain) Sichuan highlands Yunnan efficiently accumulated (mushrooms). The examined sites highly mineralized red yellow showed Hg contents ranging 0.066 0.28 mg kg−1 dry...
Tangail district is more vulnerable to heavy metals contamination for industrialization in Bangladesh.Present study describe six (Cr, Ni, Cu, As, Cd, and Pb) fifteen several sampling locations industrial vicinity of were determined.The concentration Cr, Pb studied areas soils observed 0.96-14.04, 0.71-18.39,1.02-34.44,1.2-11.21,0.44-3.31and2.01-28.86mg/kg, respectively.There representing a potential risk the environment presenting these soils.This are generally toxic soil environment.They...
Population sex ratios of many dioecious plants in nature are biased. This may be attributed to sexually different resource demands and adaptive capacity. In male-biased Populus, males often display stronger physiological adaptation than females. Interestingly, Populus Salix, belonging Salicaceae, an opposite biased ratio, especially nutrient-poor environmental conditions. Do female willows have a greater tolerance nutrient deficiency males? this study, we investigated the growth defensive...
