“…The study of metal(loid) uptake and accumulation in plants has received much interest in the last years [23][24][25][26], as they affect important physiological processes in plants, impact yield and, in the case of crops used for food and feed, can raise health-related issues. The study of metal(loid) accumulation in plants needs imaging to gain information on the sites of accumulation, on distribution and translocation routes.…”

Silicon is a non-essential element for plants and is available in biota as silicic acid. Its presence has been associated with a general improvement of plant vigour and response to exogenous stresses. Plants accumulate silicon in their tissues as amorphous silica and cell walls are preferential sites. While several papers have been published on the mitigatory effects that silicon has on plants under stress, there has been less research on imaging silicon in plant tissues. Imaging offers important complementary results to molecular data, since it provides spatial information. Herein, the focus is on histochemistry coupled to optical microscopy, fluorescence and scanning electron microscopy of microwave acid extracted plant silica, techniques based on particle-induced X-ray emission, X-ray fluorescence spectrometry and mass spectrometry imaging (NanoSIMS). Sample preparation procedures will not be discussed in detail, as several reviews have already treated this subject extensively. We focus instead on the information that each technique provides by offering, for each imaging approach, examples from both silicifiers (giant horsetail and rice) and non-accumulators (Cannabis sativa L.).

“…These toxic substances make the part of the food chain [2]. The safe feed product is essential for animal health and welfare as well as human health and healthy feed product reduce the risk of toxicity in animals and human health [3,4]. Biological functions may be affected by heavy metals especially due to bioaccumulation in the food chain because these pollutants present in the environment [5,6].…”

The pollution in the environment causes many health problems such as industrial, agriculture, mining and natural process adds many harmful substances in the surrounding and damage the environment. These toxic substances make the part of the food chain due to which livestock is at high exposure to risk. The present investigation was carried out in different district of Punjab to find out the cadmium levels in soil, forages as well as in the blood of the ruminants like goat and sheep. The cadmium contents in soil of district Sargodha, Mianwali and Bhakhar were ranged from 4.57 to 4.94, 2.98 to 3.95, 1.65 to 2.98 mg/kg respectively. The level of cadmium was higher in Sargodha as compare to Mianwali and Bhakkar. The mean concentrations of cadmium in forages which were used for feeding purpose were found between 2.745-3.432, 2.245-3.196 and 1.9-2.036 mg/kg for Sargodha, Mianwali and Bhakhar, respectively. The mean concentrations of cadmium in blood of goat which consumed the contaminated forages were between 2.152-2.436, 1.727-2.39 and 2.3-2.62 mg/L for Sargodha, Mianwali and Bhakhar, respectively. In blood of sheep, residual levels of cadmium in district Sargodha, Mianwali and Bhakhar were ranged from 2.152 to 2.436, 1.794 to 2.286 and 1.97 to 2.066 mg/L, respectively. All these values of cadmium for blood samples were within the permissible limit set by WHO.

“…Chromium is the most critical metal in an environment which has destructive effects and it is potentially harmful for dairy production system as a bioaccumulated toxin (Ugulu 2015a, b;Khan et al 2018c). The contamination in the environment is caused by chromium, and the source of this metal is tanning as well as polishing, paints, electroplating, and pigment formation.…”

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.
