What tree is suitable for biopharmaceuticals?

Trees suitable for planting flowers and plants near the chemical plant are: rose, hibiscus, zinnia, camellia, Milan, osmanthus, plum blossom, Amorpha fruticosa, mulberry, Fraxinus mandshurica, Tamarix chinensis, water wax and other trees.

Roses can absorb hydrogen sulfide, benzene, ethyl phenol, ether and other gases, and also have certain resistance to sulfur dioxide and nitrogen dioxide. Rhododendron is an ideal flower and plant to resist sulfur dioxide and other pollutants. Hibiscus is a common flower, which can absorb harmful gases such as sulfur dioxide, chlorine, hydrogen chloride and zinc oxide. Lagerstroemia indica, also known as Hundred Days Red, has a strong absorption capacity for harmful gases such as sulfur dioxide, hydrogen chloride, chlorine gas and hydrogen fluoride. Camellia can resist harmful substances such as sulfur dioxide, hydrogen chloride, chromic acid and nitric acid smoke, and purify the atmosphere. Milan can absorb sulfur dioxide and chlorine in the atmosphere. Osmanthus fragrans has special resistance to chemical smog, and has different degrees of resistance to pollutants such as hydrogen chloride, hydrogen sulfide and phenol. Plum blossoms are called "gentlemen in flowers" and have the ability to monitor the pollution of sulfur dioxide, hydrogen fluoride, hydrogen sulfide, ethylene, benzene and aldehyde in the environment.

The chlorine gas emitted is heavier, and trees such as Amorpha fruticosa, Mulberry, Fraxinus mandshurica, Tamarix chinensis and Fraxinus mandshurica have stronger chlorine resistance. In addition, it is more suitable to plant spruce, tamarisk, Robinia pseudoacacia, Salix matsudana, oak, Bai La, elm, cypress, poplar, mulberry and other tree species in factories with more dust and air dust particles, because these tree species have strong dust resistance. In densely populated downtown areas, spruce, birch, Populus davidiana, jujube, wild onion and wild garlic are most suitable for planting because of their high bacterial content. These trees all contain different degrees of fungicides, which can reduce the infection of germs. It is more suitable for planting ash, mulberry, ash, Gleditsia sinensis, oleander, willow and spruce with strong sulfur resistance.
