According to a 2021 study, dried fruits and vegetables — pineapples, apricots, mangoes, and seaweed — contain much higher lead levels than their fresh or frozen counterparts. This is because ...
This seaweed contains soluble alginates as well as alginic acid, which catalyzes the bacterial decomposition of organic matter. [1] [62] This process improves soil quality by enhancing populations of nitrogen-fixing bacteria and by supplementing the soil with additional conditioners through the waste products produced by these bacteria.

Indeed, 10 sheets of Nori seaweed contain just 9 calories and about tenth a gram of sugar. "All this makes seaweed a good choice for those watching their weight," says Goodson.
After harvest, the seaweed is dried, baled, and sent to the carrageenan manufacturer. There the seaweed is ground, sifted to remove impurities such as sand, and washed thoroughly. After treatment with hot alkali solution (e.g., 5–8% potassium hydroxide), the cellulose is removed from the carrageenan by centrifugation and filtration.
Amine gas plant at a natural gas field. Amine gas treating, also known as amine scrubbing, gas sweetening and acid gas removal, refers to a group of processes that use aqueous solutions of various alkylamines (commonly referred to simply as amines) to remove hydrogen sulfide (H 2 S) and carbon dioxide (CO 2) from gases.
[12] [13] The dried purple (nori) variation is the main plant that contains significant amounts of vitamin B 12, [12] which makes it the most suitable source of vitamin B 12 available for vegans; consuming 4 g (0.1 oz) of dried purple laver provides the RDA of vitamin B 12.
Asparagopsis seaweed, native to Australia, contains bioactives that interrupt the microbes in a cow’s stomach that form methane. It is the most efficient natural methane supplement available for livestock – capable of reducing methane emissions by more than 80 per cent in controlled conditions.
The EPA has shown that biosolids can contain measurable levels of synthetic organic compounds, radionuclides, and heavy metals. [29] [30] [31] USEPA has set numeric limits for arsenic, cadmium, copper, lead, mercury, molybdenum, nickel, selenium, and zinc. [32] The presence of heavy metals is a source of concern.
