u to tell a story and let your users know a little more about you.

Plants can be indicators of air pollution by developing pollutant-specific foliar injury or accumulating contaminants from the air. Dave McLaughlin of Cotyledon Environmental Consulting is an expert in identifying air pollution injury symptoms on plants

Cotyledon Environmental Consulting can conduct soil sampling to determine baseline soil metal levels prior to the startup of mining activities, or assess soil contaminant levels as a result of current or historic emissions
