“…In the immediate vicinity of the road (5 metres) this figure was too high -1.57 g/cm 3 . Under natural conditions, such a high density is characteristic of layers with very low permeability.…”

“…The reasons for the mechanical nature (wash and compaction by agricultural machinery) cannot explain the overfilling of the arable horizon of chernozem at a distance of 10 meters. At this point, the addition density is 1.45 g/cm 3 . As you get closer to the mark of 20 meters, the density of the composition is gradually reduced, reaching to 1.33 g/cm 3 .…”

“…At this point, the addition density is 1.45 g/cm 3 . As you get closer to the mark of 20 meters, the density of the composition is gradually reduced, reaching to 1.33 g/cm 3 . At a distance of 50 meters and further from the highway, this figure does not differ from the control.…”

“…This indicator is considered to be one of the fundamental ecological conditions of soils. Due to the annual mechanical processing of fields, the density of the plowing horizon is maintained at an optimal level-1.10-1.20 g/cm 3 .In the control area of leached Chernozem this indicator corresponds to the optimum (table.3). The remaining soils were compacted.…”

“…It should also be noted the emergence of a large number of heavy metals, soot, exhaust gases that settle on the soil and crops. This leads to deterioration in the ecological status of agrophytocenoses, fertility reductionand shortage of agricultural products [2,3].…”

The use of deicing compounds and car exhaust have a negative impact on the main indicators of arable fertility.The purpose of the research was to study the physical properties of arable land and crop yields at different distances from the roads. Four soils were studied: sod-podzolic, gray forest, leached сhernozem and meadow saline. Soil sampling was carried out along the Tyumen -Omsk and Tyumen -Khanty-Mansiysk highways. It was found that at a distance of 10 meters from the highway structural and aggregate composition of high-humus soils differs from the control, located 200 meters. At a distance of 50 meters or more from the road, physical indicators of arable land come back to normal. The sections adjacent to the roads up to 10 meters wide are overfilled to 1.57 g/cm3, which in the conditions of Western Siberia can cause surface waterlogging. The annual loss of grain from the negative impact of transport infrastructure on the site length of 1 kilometer and a width of 20 meters on leached сhernozem is 5.0 tons. At market grain prices in the amount of $140, the annual loss of farmers corresponds to $1400 for each kilometer of the road passing through the сhernozem fields.

The presence of heavy metals in milk is a public health problem that negatively effects human health, especially infant health. This study evaluated the concentration levels of lead (Pb) and cadmium (Cd) in blood and its transfer to the milk of 20 cows in production in a rural community near the La Oroya Metallurgical Complex in Peru, which has emitted fine particulate matter for more than 90 years. Validated protocols were used for sample collection. The samples were analyzed by atomic absorption spectrophotometry. The results of the analysis indicated that the levels, in mg/kg, of Pb in blood and milk were 0.38 AE 0.041 and 0.58 AE 0.018, respectively; Pb in milk was 54% higher than that in blood (P < 0.01). Cd levels, in mg/kg, in blood and milk were 0.016 AE 0.002 and 0.02 AE 0.007, respectively; milk had 28% more Cd than did blood (P < 0.05). The results for Pb in milk were compared with the Codex Alimentarius standard (0.002 mg/kg); the mean concentration of Pb in milk was 29 times higher than the acceptable limit, and the mean concentration of Cd was 2 times higher than the acceptable limit of the Romanian standard (0.01 mg/kg). The result could be attributed to the impact of environmental pollution by mining waste. In Peru, there are no norms for maximum Pb and Cd values, and the establishment of maximum value norms for these metals in milk is suggested.
