Chondrus crispus—commonly called Irish moss or carrageen moss —is a species of red algae which grows abundantly along the rocky parts of the Atlantic coast of Europe and North America. In its fresh condition this protist is soft and cartilaginous, varying in color from a greenish-yellow, through red, to a dark purple or purplish-brown. The principal constituent is a mucilaginous body, made of the polysaccharide carrageenan, which constitutes 55% of its dry weight. The organism also consists of nearly 10% dry weight protein and about 15% dry weight mineral matter, and is rich in iodine and sulfur. When softened in water it has a sea-like odour and because of the abundant cell wall polysaccharides it will form a jelly when boiled, containing from 20 to 100 times its weight of water.
Penicillium is a genus of ascomycetous fungi that is part of the mycobiome of many species and is of major importance in the natural environment, in food spoilage, and in food and drug production.
Aflatoxins are various poisonous carcinogens and mutagens that are produced by certain molds, particularly Aspergillus species. The fungi grow in soil, decaying vegetation and various staple foodstuffs and commodities such as hay, sweetcorn, wheat, millet, sorghum, cassava, rice, chili peppers, cottonseed, peanuts, tree nuts, sesame seeds, sunflower seeds, and various spices. In short, the relevant fungi grow on almost any crop or food. When such contaminated food is processed or consumed, the aflatoxins enter the general food supply. They have been found in both pet and human foods, as well as in feedstocks for agricultural animals. Animals fed contaminated food can pass aflatoxin transformation products into eggs, milk products, and meat. For example, contaminated poultry feed is the suspected source of aflatoxin-contaminated chicken meat and eggs in Pakistan.
Aspergillus niger is a fungus and one of the most common species of the genus Aspergillus.

The Pakistan Institute of Nuclear Science & Technology (PINSTECH) is a federally funded multiprogram science and technology national research institute and national laboratory site managed for the Government of Pakistan's federal ministries by the Institute of Engineering and Applied Sciences (PIEAS).
As of 2017, nuclear power in Pakistan is provided by five commercial nuclear power plants. Pakistan is the first Muslim majority country in the world to construct and operate civil nuclear power plants. The Pakistan Atomic Energy Commission (PAEC), the scientific and nuclear governmental agency, is solely responsible for operating these power plants. As of 2018, the electricity generated by commercial nuclear power plants constitutes roughly 7.5% of electricity generated in Pakistan, Pakistan is not a party to the Nuclear Non-Proliferation Treaty but is a member of the International Atomic Energy Agency. Pakistan plans on constructing 32 nuclear power plants by 2050 and envisions 40,000 MW of nuclear power generation.
