Heavy metals in seafood: maximum allowable limits

Heavy metals in seafood: maximum allowable limits

Seafood, in particular fish are a good source of protein and omega 3 fatty acids. As well these beneficial nutrients, seafood can contain trace amounts of different metals. Heavy metals present in water both naturally and introduced to the water system are absorbed by animals living in that environment. While trace elements are found in most seafood, much higher levels are found in predatory sea animals, due to the cumulative effect of their consumption. Analysis of trace metals is important to remain compliant with different countries food laws.

Trace elements in Spinach: regulations

Green leafy vegetables are good for you. They are an easy go to for a range of vitamins and minerals, including vitamin A, E and K, folate, calcium, magnesium, and potassium. While once a less desirable vegetable that needed cartoon sailors to promote it, spinach has gained popularity due to its versatility as an ingredient and nutrient density, even among other green leafy vegetables.

Modern research studies these days focus a lot on analysis of balance of trace metals in humans. Investigations have shown that many trace elements can influence human health. For example, the excess of some toxic metals or deficiency of some essential metals can be the significant factor in many physical or psychological conditions such autism.

Rapid test methods for plant analysis

Rapid test methods for plant analysis

Plant analysis provides important information about the nutritional value, quality, and current condition of plants. Inductively Coupled Plasma – Optical Emission Spectrometry (ICP-OES) and Inductively Coupled Plasma – Mass Spectrometry (ICP-MS) are two of the most used laboratory techniques. But these techniques require tedious sample preparation, more expenses, and more time. This led to the development of rapid techniques which can help in on-site decision making.

Soil test kits

Soil test kits

In any agricultural activity, the first step is soil testing. This gives information about the soil’s fertility and its physical and chemical properties. To obtain such information, analysts use soil test kits for on-site testing. Analysts can then determine if the soil is viable for planting. They can also determine what should be added to the soil to improve its fertility.

Analysing for Staphylococcus aureus

Analysing for Staphylococcus aureus

Staphylococcus aureus is facultative anaerobic, gram-positive cocci. It was named as such because of its grape-like (Greek: staphyl) forming clusters of cells and golden (aureus) colour of colonies. S. aureus can cause diseases through direct infection or indirectly by the production of toxins. This bacterium is known as a leading cause of bloodstream infections with consequences such as infective endocarditis, septic arthritis, and osteomyelitis.
