“…In several cases, overpasses or other obstructions at the midpoint location made it necessary to relocate the transect site to the next available location beyond the midpoint in the direction of the traffic flow. Midpoint locations were chosen because they offer the least chance of anomalously high values, as opposed to locations near interchanges which can exhibit higher lead levels from vehicle acceleration, deceleration and idling (Francek, 1992).…”

In order to assess the amount and distribution of lead pollution in soils adjacent to a major interstate highway serving the city of Tampa, Florida, a total of 224 samples were collected from 32 transects perpendicular to the roadway. The lead content was measured using atomic absorption spectrophotometry. The highest levels of lead were found at distances of 81, 243, and 729 cm from the road. The results show that there is a weak negative correlation between soil lead and the distance from the roadside, as well as with traffic density. The weakness of the relationship is a result of confounding variables such as turbulence and other microclimatic factors, downslope movement of soils overtime, and human action such as construction and highway landscaping. Nevertheless, over one-third of the samples collected in the study area contain more than 500 μg g(-1) lead, levels considered to be hazardous by the United States Centers for Disease Control and the Environmental Protection Agency.

“…The samples of soil, fodder and serum samples were digested by the methods of Franeck (1992), Trolson (1969) and Kolmer and colleagues (1951), respectively. The mineral content in soil, fodder and serum samples was estimated by atomic absorption spectrophotometry (ECIL 4141,Hyderabad,India).…”

A survey was conducted in 10 districts of northern India. Significant deficiency of zinc was observed in soil, fodders and (cattle) serum samples. The animals showed typical signs of zinc deficiency, namely stiff gait, swelling of hocks and knees, subcutaneous fluid accumulation, rough coat, etc. of variable intensity. A clustered model therapeutic trial was conducted and zinc-deficient cattle were divided into three groups. Group A was provided with mineral mixture containing zinc sulphate. Group B was given mineral mixture without zinc sulphate and group C was given no mineral mixture. Significant improvement (p< 0.01) was observed in the haemoglobin (Hb), total white blood cells (WBC) and total erythrocyte count (TEC) levels at the 7th day of treatment in the animals of group A. Significant improvement in enzyme serum alkaline phosphatase (SAP) was observed in group A animals at the 7th day, while improvement in asparatate aminotransferase (AST), alanine aminotransferase (ALT) and ceruloplasmin (Cp) was observed after 21 days of treatment. Regarding hormones, significant improvement was observed in thyroxine (T3) and triiodothyronine (T4), oestrogen and progesterone in group A animals within 14 days of treatment. The values of vitamin A showed a highly significant (p < 0.01) improvement within 7 days of treatment in group A animals and that of vitamin E on the 21 st day of treatment. The milk yield of lactating cattle and body weight of growing calves in group A showed highly significant (p < 0.01) increases at about 14 and 30 days, respectively. It is concluded that zinc sulphate supplementation is highly effective in alleviating zinc deficiency and improving various biochemical and production parameters in cattle. The clustered model treatment provides a better indicator of the most limiting element under field conditions where simultaneous deficiency of various minerals is prevalent.

“…Lead is a persistent toxic heavy metal to humans, which has been considered by the International Agency for Research on Cancer (IARC, 1993) as a possible human carcinogen (group 2B) (Francek, 1992;Silbergeld et al, 2000). Exposure to lead can cause direct DNA damage, clastogenicity, or inhibition of DNA synthesis and repair, and it is particularly toxic to the central nervous systems of children (Juberg et al, 1997;Silbergeld et al, 2000).…”

Effect of selenium fertilization on the accumulation of cadmium and lead in rice plants

et al. 2014

Background and Aims The accumulation of cadmium and lead in rice (Oryza sativa L.) grains is a potential threat to human health. In this study, the effect of selenium fertilization on the uptake and translocation of cadmium and lead in rice plants was investigated. Methods Rice plants were cultivated using cadmium and lead contaminated soils with selenium addition at three concentrations (0, 0.5 and 1 mg kg −1 ). At maturity, plants were harvested, and element concentrations in rice tissues were analyzed by using ICP-MS.Results Selenium application significantly increased seleniumaccumulationinricegrain,andmarkedlydecreased cadmium and lead concentrations in rice tissues. In brown rice grains, selenium application reduced cadmium concentrations by 44.4%, but had nosignificant effect onlead accumulation. Selenium application significantly decreased metal mobility in soils, at 0.5 mg kg −1 treatment, the translocation factor of cadmium and lead from soil to ironplaquedecreased by71and 33% respectively. Conclusions The mechanism of selenium mitigating of heavy metal accumulation in rice could be decreasing metal bioavailability in soil. Selenium fertilization could be an effective and feasible method to enrich selenium and reduce cadmium levels in brown rice.
