This also is true of air pollutants in that their impact on organisms occurs only when the pollutants are placed in solution (e.g., in the human lung).

In addition, tailoring the product to the customer’s needs is becoming increasingly important in quality improvement. These trends are resulting in production in small batches, which are driven by customer orders. Detail
