The present investigation was performed in different district of Punjab to determine the chromium level in soil, forages, and blood plasma of the small ruminants (goat and sheep). The results showed that the mean concentrations of chromium in the soil of Sargodha, Mianwali, and Bhakkar districts were ranged from 1.8 to 2.3, 3.01 to 4.99, and 2.04 to 2.87 mg/kg, respectively. The chromium level was higher in Mianwali compared with Sargodha and Bhakkar. The mean concentrations of chromium in forages which were used for feeding purposes were found between 0.672 and 1.631, 1.493 and 2.612, and 0.7804 and 1.047 mg/kg for Sargodha, Mianwali, and Bhakkar, respectively. The mean concentrations of chromium in blood plasma of goat which consumed the contaminated forages were between 0.666 and 1.269 mg/L in Sargodha, 0.657 and 0.752 mg/L in Mianwali, and 1.39 and 2.37 mg/L in Bhakkar. In blood plasma of sheep, the residual levels of chromium in the districts Sargodha, Mianwali, and Bhakkar were ranged from 0.673 to 1.384, 0.83 to 1.086, and 1.496 to 3.611 mg/L, respectively. In the present research, there was a higher concentration of chromium in blood plasma of sheep from Bhakkar and the lowest was in Sargodha. The chromium level in blood samples was found to be higher than the tolerable level of 1.0 mg/L in all districts. In light of these results, it was concluded that chromium levels in the soil and forages of all sites were present within the safe limit while in blood samples of sheep and goats were found to be above the acceptable limit. Sheep and goats also consume water from river, streams, and ponds and other contaminated water sources. So it might be the reason of higher level of chromium in their blood plasma. Hence, the proper monitoring of study sites will be necessary to prevent the excessive accumulation of chromium in ruminants in the near future.

“…Since the availability of clean freshwater is becoming increasingly limited, more and more places use wastewater for irrigation. In addition to containing valuable macro-and micronutrients, which in optimal concentration might be beneficial for plant growth and development [1], domestic wastewater might also contain a considerable amount of non-biodegradable HMs, which in excess, are able to accumulate in the food chain, potentially causing toxicity symptoms [2,3]. Among the many possible contaminants, cadmium (Cd), chromium (Cr), copper (Cu), lead (Pb), mercury (Hg), nickel (Ni), and zinc (Zn) are the most concerning toxic HMs [3], whose properties and effects on plants are discussed in the Supplementary Materials (Table S1).…”

Metal-polluted areas, especially where municipal sewage is used as fertilizer, often have high concentrations of more than one metal. The development of the root system is regulated by a complex signaling network, which includes reactive oxygen and nitrogen species. The delicate balance of the endogenous signal system can be affected by various environmental stimuli including heavy metals (HMs) in excess. Our goal was to analyze the microelement homeostasis, root architecture, and to determine the underlying changes in the nitro-oxidative status in the root system of rapeseed (Brassica napus L.) and sunflower (Helianthus annuus L.) subjected to combined HM treatments. The effect of model-sewage in two different layouts was simulated in rhizotron system by only supplementing the highest HM concentrations (Cd, Cr, Cu, Hg, Ni, Pb, and Zn) legally allowed. The two species reacted differently to combined HM treatment; compared to the relatively sensitive sunflower, rapeseed showed better metal translocation capability and root growth even at the more severe treatment, where the pattern of protein tyrosine nitration was reorganized. The obtained results, especially the increased nitric oxide content and changed pattern of tyrosine nitration in rapeseed, can indicate acclimation and species-specific nitro-oxidative responses to combined HM stress.

The by-product of industrial and municipal wastewater is sewage sludge. It is enriched with a lot of organic nutrients. The sewage sludge that has high amount of organic matter, micronutrients, and macro-nutrients, are usually used as fertilizer for horticultural crops. The impact of sewage sludge on heavy metal's uptake ratio by wheat variety is observed by conducting a pot experiment. The amount of heavy metals in various parts of wheat plant was analyzed by atomic absorption spectrophotometer (AA-6300 Shimadzu Japan). The metals concentration in grains of wheat ranged from 0.64 to 0.97 for Zn, 0.76 to 0.93 for Co, 1.30 to 1.61 for Cd and 0.81 to 1.58 mg/kg for Fe, respectively. All metal concentrations were found below the permissible limits suggested by FAO/WHO. The calculation for translocation and bio-concentration factor for various parts of the wheat crop was done. However, there may be a risk of the presence of potentially unsafe substances in the sewage sludge e.g., pathogens and heavy metals.
