“…Chromium oxide was used to coat metal weapons in the Chinese Empire for more than 2000 years. Chromium was discovered as an element in 1761 and was first used as a pigment [113]. In 1797, chrome metal was separated from its ore for the first time.…”

In the era of industrialization and technological progress, pollution has reduced the quality of life for humans. Heavy metal pollution is one of the main causes of environmental degradation. The underlying causes are natural as well as human. Heavy metal contamination of soil has become a worldwide environmental issue that has attracted considerable public attention, mainly due to increased concern for the safety of agricultural products. Heavy metals refer to some metals and metals with biological toxicity such as cadmium, mercury, arsenic, lead and chromium. These elements enter the soil agricultural ecosystem through natural processes resulting from raw materials and through human activities. Heavy metal pollution is a great threat to the health and well-being of animals and humans due to the risk of potential accumulation through the food chain. The main sources of heavy metal pollution are air pollution, river sediments, sewage sludge and municipal waste compost, agricultural chemicals such as fertilizers and pesticides, and industrial wastes such as factories that release chemicals. Heavy metals can enter the water supply through industrial and consumer wastes or even from acid rain that decomposes soils and releases heavy metals into streams, lakes, rivers and groundwater.

“…Chromium is a heavy metal that often causes agricultural land degradation. Chromium is mostly applied in modern industries such as tanning, iron casting, pharmaceutical industries, metallurgical industry, textile dyes, paint industry, metal refining and others [4], [5] which are then disposed of inappropriately into irrigation flows so that they can enter agricultural land, accumulate in the soil and cause toxicity to plants, animals and humans [6], [7]. Hexavalent chromium (Cr (VI)) is carcinogenic, teratogenic and mutagenic which can cause ecosystem damage, and if it enters the food chain, it will harm human health [8].…”

Biofilm are microbial community that attaches to one substrate and another through EPS. Functional microbes in biofilm can be used as a biofertilizer which increase plant growth by providing nutrients and plant resistance to pathogens due to agricultural environmental degradation. Beside being a biofertilizer, biofilm can be developed as a bioremediation agent. Hexavalent chromium (Cr (VI)) is a heavy metal that is widely used in the leather tanning, pharmaceutical and metallurgical industries, so it is easily found in irrigation and causes agricultural land pollution. Chrome can be toxic to microorganisms, plants, animals and humans, because it is carcinogenic, causes ecosystem damage and has a negative impact on human health. Various techniques are used to remediate Cr (VI), one method that can be used is bioremediation by exploiting the potential of bacteri or fungi incorporated in the biofilm. In this study, the biofilm consisted of bacterial and fungi (BFBF) that were found on the western slopes of Mount Lawu. The Cr (VI) reduction test was carried out at concentrations of 5 and 50 mg L−1. The results showed that the biofilm was able to reduce Cr (VI) up to 1.19 mg L−1within 6 hours.

“…Zinc and copper play a role in biological processes based on their amounts and are among the essential elements for biological reactions; however, the increased bioaccumulation of these two metals in body tissues causes their high toxicity (6). High levels of chromium cause stomach ulcers, respiratory problems, weakened immune systems, kidney and liver damage, lung cancer, and mortality in humans (7,8).…”

Background & Aims of the Study: Heavy metals are among the most dangerous environmental pollutants entering the air, water, and soil through human and natural activities with the potential of poisoning, pathogenicity, and carcinogenicity to living organisms and humans. The current study aimed to determine the contamination of heavy metals, including lead, zinc, copper, arsenic, chromium, and cadmium, in the surface soils of Ahvaz, Iran, using pollution indicators and health risk assessment. Materials and Methods: Sampling of surface soils in Ahvaz with 227 soil samples was performed in August 2017 based on the regular networks of 1 × 1 km. The measurement of heavy metals was carried out by inductively coupled plasma optical emission spectrometry. Results: The mean concentrations of Pb, Zn, Cu, Cr, Cd, and As in the surface soils of Ahvaz were reported as 180.99, 88.61, 185.13, 101.59, 5.63, and 8.97 mg/kg, respectively. Based on the contamination factor (CF), pollution index (PI), geoaccumulation index (Igeo), and ecological risk, the highest levels of pollution were related to Cd and Pb, and the lowest level was associated with Cr. The enrichment factor (EF) of heavy metals showed moderate contamination of Cr, high contamination levels of Cu, Cd, and As, and very high contamination levels of Pb and Zn. According to the Nemro Integrated Pollution Index (NIPI), 3% and 55% of the surface soils of Ahvaz showed high and low levels of pollution, respectively. The daily absorption of heavy metals through ingestion in children and adults was higher than that through respiration and dermal contact. The highest risk index was related to Cr and As through ingestion for children, and the lowest risk index was associated with Zn through respiration in adults. Conclusion:The levels of As, Cr, and Cd in the surface soil of Ahvaz were higher than the Iran soil standard values; however, the levels of Pb, Zn, and Cu were lower. Based on the CF, PI, Igeo, and ecological risk, the surface soils were highly contaminated with Cd and Pb. According to the EF, Pb and Zn showed the highest levels of contamination. Based on the NIPI, the pollution of heavy metals was reported at low levels. The highest and lowest values of metals carcinogenicity were related to Cr in children and Pb in adults, respectively.
