For example, although there are numerous benefits to urban greening, such as reducing the urban heat island effect while simultaneously promoting an active healthy lifestyle, 248,310,311 the urban planting of certain allergenic pollen producing species22 could increase human pollen exposure and allergic illness.

They are Ambrosia trifida, or giant ragweed — a plant as ugly as its name and as useless, well, as its cousin, common ragweed, A. artemisiifolia, a machine for sucking up water and spewing out highly allergenic pollen.

The most allergenic pollen comes from non-flowering trees, grasses, and low - growing weeds.

Not exact matches

The effects of increased temperatures and atmospheric CO2 concentration have been documented concerning shifts in flowering time and pollen initiation from allergenic plants, elevated production of plant - based allergens, and health effects of increased pollen concentrations and longer pollen seasons.15, 16,17,18,19,20,21,22,23,24,25,26 Additional studies have shown extreme rainfall and higher temperatures can lead to increased indoor air quality issues such as fungi and mold health concerns.27, 28,29,30

Climate change, resulting in more frost - free days and warmer seasonal air temperatures, can contribute to shifts in flowering time and pollen initiation from allergenic plant species, and increased CO2 by itself can elevate production of plant - based allergens.137, 15,16,17,18,19,138 Higher pollen concentrations and longer pollen seasons can increase allergic sensitizations and asthma episodes, 20,21,155,22 and diminish productive work and school days.138, 22,23

Allergenic plants grown at elevated carbon dioxide produce more pollen over a longer pollen season than those grown at ambient levels (78).

Pollution not only increases the pollen load, but it makes pollen more allergenic, causing grass pollen, for example, to express more of its allergy - inducing proteins.

Climate change, resulting in more frost - free days and warmer seasonal air temperatures, can contribute to shifts in flowering time and pollen initiation from allergenic plant species, and increased CO2 by itself can elevate production of plant - based allergens.137, 15,16,17,18,19,138 Higher pollen concentrations and longer pollen seasons can increase allergic sensitizations and asthma episodes, 20,21,155,22 and diminish productive work and school days.138, 22,23

Since some plants have pollen that is highly allergenic, this could mean increased exposure to allergens and an increase in illness for those who are pollen allergic.
