Understanding supply networks and Risks Marine Toxins in Pet

Humans often throw plastics and sewage in the river and the sea waste. Action is not responsible for this , but ultimately be damage human body by eating fish and marine animals live in waters. Food Network will help you understand it.

The net food is the relationship between the food chain with another food chain in an ecosystem. The food chain is composed of a living being that consume other living beings. Therefore a living being can have more than one type of food and living things can be eaten by more than one other living beings, then food webs formed.

Examples of single-phase networks food that originated from plants can be described as follows.

• Plants use sunlight to form seeds, leaves and fruit.
• plants, for example grass, then consumed by cattle as herbivores or consumer level 1.
• Ox is consumed by humans and then as a level of consumption of 2 or carnivores or the top of the consumer.
• the body of the dead man described by worms and other bacteria are then used to develop plants.

The webs of these foods are also in the sea, the fish were initially consume plankton is eaten by humans. The problem then arises waters are polluted Currently, these fish not only feed on plankton, but also garbage and debris in the area.

In Jakarta alone, in June 2014, thousands of fishermen complained Kalibaru Cilincing changes in the original sea water, dark green, turning black. These changes are then allegedly caused by the disposal of waste from factories in the region. These conditions led to the fish usually caught in a dead floating. While in 2015, about 750 kilograms of fish died in vain along the beach in Ancol, North Jakarta. It is not known how long this pollution has taken place. Whereas before, the places used as a source of fish supply in the markets of Jakarta.

The seafood fabrics and dangerous chemicals

Varying the consumption of fish and marine animals is necessary to satisfy the needs of protein, vitamins, minerals and fatty acids omega-3 . But now, after understanding the food chain, we understand that what is consumed by the animals to be consumed by humans at risk of causing health problems in humans.

Contaminants are generally human waste chemicals do not dissolve. Once released into nature, this material accumulates in the food chain, causing disruption of all living things they consume, including humans.

These contaminants still remain in the body of marine animals until eventually consumed by humans. An example is mercury. Most of the mercury in fish can actually be tolerated by the body, but most marine animals and fish can contain high levels of mercury. At these high levels, children and pregnant women to be at greatest risk of negative effects.

Mercury at high levels can damage the brain and nervous system of the fetus. When humans eat contaminated fish, mercury is well absorbed in the body and cause disruption in high doses. Over time, mercury is outside the body through urine, feces, and breast milk.

Risk Reduction

If you are not sure if fish or marine animals that will be consumed completely free of mercury and polluting more, it is good to take the following measures .

• Avoid high risk of containing mercury fish such as mackerel, swordfish, shark, carp, and needle.
• limit consumption of canned tuna.
• limit consumption of marine animals are at risk of exposure to hazardous chemicals at sea, such as scallops, grouper, halibut, lobster, dorado.
• Avoid fishing for consumption in areas at risk of exposure to mercury.
• Be careful when eating sushi. Be sure to eat in a place that is clean so you are sure that the fish served is safe for consumption.

Meanwhile, fish and marine animals that are suggested are shrimp, tuna, squid, salmon, sardines, and crabs.

In addition to mercury, you should also be aware of pesticide contamination that can contaminate freshwater fish in the farmland around. In addition, other contaminants are widely available in Indonesia is infrequently plastic waste bisphenol A (BPA) is not contained.

Over time, plastics have reached the sea and degraded into smaller fragments, because exposure to sunlight, waves, and oxidation. The study found that chemicals in the plastic can be absorbed and remains in the body of marine animals. If these marine animals for human consumption, so mikroplastic particles can be absorbed into the placenta of pregnant women, gastrointestinal glands and lungs, and blood in the brain. Although the review is in need of further research, but it helps reduce the risk with steps above.
