💡 Detailed Explanation
「～にとどまらず」 means "not only... but also..." or "not limited to...". It emphasizes that the scope or influence of something extends beyond a certain range. Here, the technology's contribution extends from the medical field to environmental issues. 「はもとより」 is similar but often implies the first item is obvious or expected. 「にとどまらず」 better captures the sense of expansion. 「を問わず」 means "regardless of". 「かたわら」 means "while doing A (as a main activity), also do B".
