Until recently, most people were convinced that any berries are exclusively divided into edible and inedible, and there is simply no other gradation of these natural gifts. For the time being, this was the case - if the SS ecology is all right, and the plants grow in a suitable place where there are no pollutants, their fruits and berries can only be either poisonous by nature and inedible due to their species and morphology , or completely edible, and, importantly, useful to any person.
However, due to the worsening environmental conditions in the majority of the planet’s territories, a third type of berries appears - infected ones. They may look like edible and be inherently them, but carry a whole range of harmful substances. Heavy metals, chemicals - all this and much more can accumulate in any fruit with all the ensuing consequences for those who decide to eat them. Today, with this aspect you need to be as careful as possible - so as not to encounter sudden unpleasant surprises.
Fortunately, in most cases, the presence of chemistry in the fruits or berries can be predicted. As a rule, a distortion in the shape of the fetus, a change in its color or taste, the presence of black dots and other signals testify to trouble. If there are many fruits that attract attention due to their atypical nature, it is worth abandoning their collection in this territory in favor of a cleaner area. However, it is not always possible to find out about the danger on the fly - after all, sometimes the risks remain simply invisible. So, recently a new type of pollution has appeared, which was previously almost unknown, and its distribution was minimal. This is a phenomenon such as radiation. If in the past it could have only natural origin, now, thanks to human activity, it can turn out to be artificial, caused by certain events. Nuclear testing and the search for new fuels, working with them, industry and production, and even much more, such as burning coal - all this can release a certain amount of radiation and allow it to spread in the surrounding territories. This is very dangerous - the radiation spreads very quickly, with soil, water and even air.
To identify a hazardous area or product, the same fruits must be used , since it will not be possible to visually verify this.
