“…Composting can biodegrade organic matter and produce substances that affect the mobility of heavy metals. The addition of phosphate amendments during sewage sludge composting also contributes to better fertilizer efficiency and heavy metals passivation, creating compost that are safe for agricultural applications [29].…”

The management of solid waste presents a challenge for developing countries as thegeneration of waste is increasing at a rapid and alarming rate. Much awareness towards thesustainability and technological advances for solid waste management has been implemented toreduce the generation of unnecessary waste. The recycling of this waste is being applied to producevaluable organic matter, which can be used as fertilizers or amendments to improve the soil structure.This review studies the sustainable transformation of various types of biomass waste such as animalmanure, sewage sludge, municipal solid waste, and food waste, into organic fertilizers and theirimpact on waste minimization and agricultural enhancement. The side effects of these organicfertilizers towards the soil are evaluated as the characteristics of these fertilizers will differ dependingon the types of waste used, in addition to the varying chemical composition of the organic fertilizers.This work will provide an insight to the potential management of biomass waste to be produced intoorganic fertilizer and the advantages of substituting chemical fertilizer with organic fertilizer derivedfrom the biomass waste.

“…The use of pesticides and artificial fertilizers leads to environmental pollution with toxic metals. They pollute the soil, plants, and, subsequently, meat, which is a threat to humans [5]. Urbanization results in the deterioration of environmental pollution, as well as inadequate waste management.…”

“…A serious food safety problem is the presence of toxic metals in meat, a small amount of which is a hazard to humans [ 5 ]. Elements classified as toxic metals are lead (Pb), mercury (Hg), cadmium (Cd), arsenic (As), zinc (Zn), cobalt (Co), chromium (Cr), manganese (Mn), iron (Fe), barium (B), lithium (Li), zirconium (Zr), selenium (Se), molybdenum (Mo), aluminum (Al), and copper (Cu) [ 6 , 7 ].…”

“…Meat and meat products are contaminated with metals mainly from the environment, as well as from industrial waste. Contamination with lead and mercury occurs most often in the case of environmental pollution, usually from mines, or waste gases, as well as pesticides and herbicides used on pastures [ 5 ]. According to Das et al (2021) [ 8 ], livestock may be a threat to the toxic effects of arsenic through the consumption of animal products and meat.…”

The aim of this review is to comprehensively present disorders of the reproductive system in cattle exposed to contact with toxic metals. Toxic metals are a common environmental pollutant and can come from mines, smelters, fossil fuel combustion, or volcanic eruptions. Metals have the ability to bioaccumulate in living organisms, thus contaminating the food chain and may pose a threat to humans. They accumulate mainly in the liver and kidneys, but also in muscles and fat tissue. Toxic metals such as lead (Pb), arsenic (As), mercury (Hg), and cadmium (Cd) have a negative impact on the fertility of animals; they can lead to abortions, premature calving, or oocyte dysfunction. Moreover, in the male reproductive system, they disrupt spermatogenesis, and cause apoptosis of sperm and oxidative damage. The main source of exposure of livestock to toxic metals is through the consumption of feed or contaminated water. It is important to monitor the level of heavy metals in animal products to prevent human poisoning. Toxic metal biomonitoring can be performed by testing urine, blood, milk, plasma, or hair. Chromium (Cr), arsenic (As), and cadmium (Cd) are excreted in the urine, while lead can be detected by examining the blood of animals, while in milk, arsenic (As), cadmium (Cd), nickel (Ni), and lead (Pb) can be detected. Moreover, toxic metals do not biodegrade in the environment. To purify soil and waters, remediation methods, e.g., biological or chemical, should be used.
